Send to email isn't working, is there a fix?

I receive this error notice when I try to send a document to email. “An error occurred in sending the message. Possible errors could be a missing user account or a defective setup. Please check the LibreOffice settings or your e-mail program settings.”

Windows 10 x86
LibreOffice 5.4
Java 8 update 151
Mozilla Thunderbird

OK update LibreOffice 6 was the fix.
